y ieiaaie PIPE CEDAM?.

Application filed September vThis iuventionrelatcsto improvements in attachments adapted to be mounted in association with pipes and the like to prevent leakage of matter through any apertures which may have been formed'therein.

An important object of the invention is to provide-a pipe clamp which may be quickly and conveniently mounted upon a pipe and will efficiently close any openings through which the matter being conducted by the pipe, mayV escape.4

Another object of the invention is the provision of a. pipe clamp of the above character which may be very securely positioned upon the pipe without great difficulty.

Still another object ofthe invention is the provisioniof an'eiicient and easily operable pipe clamp ofsimple and du able designand which may be placed upon the market at a relatively low cost.

@there objects and advantages of this invention will become apparent as the description progresses.

In the. accompanying drawingformingY a part of thisspeciioation and in which like numerals are employed to designate corresponding :parts throughout the same:

Figure I'is aside elevation of a clamping apparatus constructed in accordance with my inventiom shownin association with a pipe section,

Figure 2 is an end.y elevation of the same,

Figure 3 is a transverse sectional view taken on thc line 3-3 of Figure 1, and

Figure 4 is top planview of the same.

In the drawing, wherein for the purpose. of illustration is shown the preferred embodiment of my invention7 the numeral 10 generally indicates my improved clamp de vice composed of an upper section 11 and a lowered-acting section 12. In carrying out my invention, it is intended to so connect these sections in association with a pipe or hose, as toy cause-the members to be tightly positioned over an opening which may be formed in the pipe so as to render the pipe lealtproof.

3referring nowl moreV specilically to the structure embodying my invention, it is to be noted that the lower section 12 embodies a bottom plate 13 of substantially semi-circular formation adapted to firmly embrace the lower portion of a pipe. Formed integral with the plate 13 and extending upwardly from the edges thereof are a pair of side plates or cars 14- preferably positioned at 14, 1925. sei-iai No. 56,393.

the central portion of the plates 13'andl arranged in parallel positionsat each side of the pipe. Each of these plates is provided with an aperture adjacent its upper edge, these apertures being in transverse alignment and one ofthe side plates or ears is further providedwitli aA vertical` internally threaded bore communicating" with theisaid aperture. This bore is intendedttoreceive a set screw 15 having formed on its upper extremity an enlarged headl providedwith av transverse bore, the purpose of which will hecomc apparent as the description progresses.

The upper co-acting section 1'1 is composed cfa top plate 17 of substantially the same length as the bottom plate 12 and adapted-to be positioned in opposed relation thereto. rThis plate` is also of arcuate formation prefcrably in the form of a quadrant in cross section. Formed on the top at the central por tion of the plate 17 is a seat structure 18 provided with l a transversely extending arcuate recess 19` for engagement with. a suitable fastening element which will be presently described.` Formed on one end* of the top plate 17 and extending laterally from the edges thereof are a pair of tapered ribs 20sliown to advantagein Figure 4i, these ribs being adaptedto bear against the side plates or ears 1.4i andpreventf longitudinal movement of the plate.

The foregoing' sections are preferably con structed of durable metal or similar material adapted to conform to the contour of the pipe and to be firmly pressed in position thereon. llVhile I have not considered it necessary, attention is invited to the fact that suitable packing material: of' conventional design may be positionedbetweenthe plates and pipes for more effectively clamping the pipes when desirable.

In order to tightly compressythe clamp sections upon the pipes andretain' thesel coacting members in this position, I provide a transverse shaft 21 engageable with the openings formed in the ears 14C, this shaft being secured in position by means of the set screw 15 and prevented against' accidental displacement. Itotatably mounted upon the shaft 21 is a cylindrical sleeve 22, this sleeve being provided with an eccentric longitudinally extending bore 23. As is obvious from the drawing, the sleeve 22 extends vbetween the inner edges of the side plates and is freely rotatablc about the shaft 21. This sleeve fili' is slidably engageable with the seat 18 and upon rotation exerts a cam action on the sections, due to the eccentric positions of the shaft 2l.

In order to facilitate the rotatable movement of the sleeve a transverse bore is drilled through a portion of the sleeve and the shaft, this bore being in alignment and engageable with a pin 23. The upper end of the pin is provided with an enlarged head 24 through which is formed a transverse opening adapted to receive a removable rod 25. This construction will enable the sleeve to be readily rotated se as to firmly press the sections upon the pipes. When the proper adjustment is obtained, the shaft is held against further movement by rotation of the set screw 15 and the clamp securely held in position.

As can be readily seen from the foregoing description and the drawings, a clamping apparatus of extremely simple and durable design is provided. The structure is arranged so as to be conveniently attached upon the pipe and may be firmly wedged in association therewith.

It is to be understood that the device is susceptible of modification and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention, or the scope of the subjoinedclaims.

Having thus described my invention, I claim:

l. An apparatus of the class described including a pair of co-acting sections, the bottom section embodying a curved plate, a pair of parallel ears formed on the sides of the plate, the upper section embodying a curved plate in opposed relation with the bottom plate, a seat formed on the upper plate, and an eccentrically mounted rotatable member engageable with the seat formed on the upper plate adapted to torce the member tightly in engagement with a pipe section orthe like.

2. A pipe clamp comprising, in combination, a pair ol co-acting sections, the lower section embodying a curved bottom plate adapted to firmly engage the lower portion oi' a pipe section, a. pair olf vertically extending cars form-ed on the lower plate and extending at the sides oi the upper section, an upper section en'ibodying a curved plate disposed in opposite relation with the bottom plate, a seat having a curved recess formed on the top plate, a transverse shaft mounted in and extending between the bottom plate ears, a sleeve rotatably mouiited on the shaft, and means for conveniently rotating the said sleeve and shaft.

A pipe clamp comprising a lower sec` tion embodying a curved bottom plate, a pair of ears forme-d on the upper edges oi the bottom plate and extending vertically upward. a eo-acting top section embodying a curved top plate, a seat having an arcuate recess formed on the central portion of the top plate, a shaft rotatably mounted in suitable openings formed in die ears, a sleeve having an eccentric bore rotatably mounted on the shalt, means for readily rotating the said sleeve and shaft and causing the sleeve to lirmly engage the seat formed on the top plate, and means for securing the shaft against movement.

4. A pipe clamp comprising, in combination, a pair ot co-acting sections, the lower section embodying a curved bottom plate engageable with the bottom portion of a pipe section, a pair of ears formed on the edges of the bottom plate and extending vertically in parallel positions, the top coacting section embodying a curved top plate disposed on the upper portion of the pipe section in opposed relation to the bottom plate, a seat formed on the central portion of the top plate having an arcuate recess, a transversely extending shaft mounted through suitable openings in the parallel ears, a sleeve rotatably mounted on the shaft having' a longitudinal bore engageable with the shaft, the said bore heilig formed eccentrically in the sleeve, a pin adapted to engage an aligned bore formed in the central portion of the sleeve and shaft, for rotating the shaft, the central portion of the sleeve being .firmly engageable with the seat formed on the top plate for 'forcing the sections tightly on the pipe, and a set screw threadedly mounted in one or" the ears :tor securing the shaft in locked position.

5. In a pipe clamp, a pair of coacting pipe engaging sections adapted to embrace a pipe, a transverse shaft mounted in opposed projections lormed on the upper tion, an eccentric sleeve. rotatably mountedv on the said shalt cngageable with the uoacting section, and means hereby the sleeve may be rotated to con'lprcss the sections about the pipe.
